To all whom it may concern I Be it known that I, Francesco Gnnovnsn, a citizen of the United States of America, residing at New Yorkcity, countyand State of New York, havein-vented anew anduseful Macaroni-Press, oi which the following is a. specification.

'My invention relatesto presses ctor macaroni and materials oi a like manner.

Special objects of the invention are to provide improved mechanism for automatically stopping the plunger of the press at the ends of its stroke, and to provide simplified and improved quick-return mechanism for rapidly feeding the plunger.

The invention accordingly comprises autoinatic stop mechanism for limitingithe movements of the plunger consisting of power shut-01f devices, and latches controllingthe same and disposed in position to "be actuated bythe plunger, and combined power feeding and quick-return mechanism consis'ting of a drivesha ft geai'edtothe plunger and having both a relatively slow worm gear drive for the power movement, and a relatively fast drive forthe-qu'ic'k-return movement.

0ther features and details of the invention will appear as the specification proceeds. I The accompanying drawings illustrate the invention embodied in a practical *commercial form, but I- will'have it understood that changes and modifications may be made without departure from the true spiritand scope of the invention.

In these drawings:

Fgure 1 is a vertical sectional view of the machine taken substantially on the plane of the line 11'o'f Fig. 2.

Fig. 2 is a sectional plan, view of the machine taken substantially on theline 22 ofFigl.

ig. 3is a broken rear view of the ma chine. v

Fig. 4 is afragmentary detail view'of the latch for holding the clutch lever in th clutch-engaged position. v

The machine illustrated comprises in general a die -5 having a plunger 6 cooperating therewith and operated byzaiscrew 7 working in a nut block *8 forming a part of the frame 13 of themachine;

The plunger screw 'is driven by a relatively large gear 9 having a driving hub or sleeve 10 longitudinally slotted at 11 to receive a transverse key 12 projecting from the screw shaft 7. "This construction pro} vides a sliding driving connection between the gear and screw shaft-allowing for the longitudinal feeding movement of the screw;

The gear 9 is shown as of the internal drive type and is operated by a pinion 14L engaged therewith and mounted on the upper end of an upright drive shaft 15. During the downward or power stroke not the screw operated plunger, ithis upright drive shaft is drivenat la -relatively slow rate'of speed by means *here comprising a worm gear '16 on said shaft, and'a Worm I? on an -adjoining power shaft 18. iPower is applied to this shaft as by meansmi the belt 19, said belt-being *shiftable into en'gagemmt with either' the fast or the loose pulleysflt) or 21 tor controlling the application of such power.

uring the slow feeding movement, 'the worm gear is clutched to the drive shaft I5 by means, consisting "in "the present disclosure, of a clutch member QIfZ'slidabl y keyed 0n the drive shatt as indicated at 2-3, and provided on its upper' end "with "clutch jaws 24 for engagement with corresponding clutch jaws-25 on the loweriiface ofthewvorm gear. lhis movable clutch element is shifted into engagement with the'worm gear clutch element by a shifting lever 26 pivotally sup ported onthe frame at'27 and extendingiorwardly within easyreach otthe operator of the =machine.

"Preferably, means are provided for latchso as to thereby lock the lever "in shifted position,

At the end-of its downastroke the plunger is automaticallystopped bynieans *compris ing a trip lever 29 pivotally supported attO having an annular portion "31 surrounding the gear sleeveltlin position tobe engaged and depressed by'the transverse key 12, --and connected'at its opposite end'w'ith a spring pressed latch member 33 which holdsthe spring actuated "belt shifting slide 84 in the position to which it is shifted by the handle 35. y In startingthe machine the 'powerycontrolling lever 35 "is operated to shift the slide3 l against the tension of its spring*36, said 'slide carrying a *belt guide 37 encircling the drive belt 19. The belt is thereby ing slide is retained in the position to which theplunger-is desired, the belt shifting slide and as this is accomplished, the spring pressed latch drops into an opening or keeper 38 provided for it in the slide. Power is then continuously applied until the 5 plunger reaches the limit of its downward stroke whereupon the latch is automatically retracted in the manner above described and the spring 36 operates the belt shifter to carry, the belt back on to the loose pulley.

A quick-return feed is provided for the plunger in the form of aflquick-return power shaft 39 connected with the upright drive shaft 15 as by means of bevel gears 40 and 4:1, and provision is made for quick-feeding of theplunger in both directions byv providingreversely operating drive belts 42 and 43 for operating this power shaft, said belts normally travelii'ig over the loose pulleys 44 and 45, and arranged to be shifted by a suitable belt shift onto the intermediate fast pulley' l6. This belt shift is shown as a slide 4.7 carrying guides 48 for the respective belts, said slide being acted upon by a spring 49 to return it to the intermediate position indicated in Fig. 3. This belt shiftit is shifted by a spring pressed latch 50, and this latch isgautomatically released at the end of theupward feeding movement of the plunger by means of a pivoted trip lever 51 disposed in thepath of the plunger and connected-with the latchat 52. V

The quick-return movement of the plunger is effected by shifting the belt guiding slide in the proper direction to carry the ley on to the intermediatefast pulley. The clutclr2425 isuncoupledat this time so thatf'the .worm gear is inoperative. The gearing 40-11 is so proportioned and the shaft 39 is rotated at such speed that the drive shaft'will berotated at a relatively rapid rate producing thereby a relatively uick return of the screw operatedplunger. Asthe plunger nears the limit of its upward stroke it contacts with the trip lever 51 which releasesthe latch 50, permitting the spring operated slide to shift the belts l2 and 43 back again onto their loose pulleys. If a rapid downward or feeding movement of is merely forced in theopposite direction from that previously described, to carry the reversely running belt onto thefast pulley 46; The plunger may then be fed as far as desired', the feeding movement being stopped by releasing the latch 50 and permitting the spring operated belt shift to again carry the belts into the neutral position. This latch .50 may be automatically released at the end of the downward feeding stroke of the plunger as by providing a connection 53 from the trip annulus 31, overstanding the downward feeding belt from its loose puling operated by the slow power feed or the quick-return feed. The quick-return feed mechanism may be utilized to feed the plunger in both directions and isxreadily controlled for such purposes. The slow power feed mechanism is easily controlled and may be locked in the operative position, and both the slow feed and the quick feed mechanisms are of simple construction and operate quietly and efficiently.

I claim; j g 1. Incombination with a screw operated plunger, a gear connected with said plunger, a drive shaft disposed in parallel relation to the plunger, a pinion-011 one end of said drive shaft engaged with the gearof the screw plunger, a gear on the opposite end of the drive shaft, a quick return shaft and a gear on 3 said quick return shaft in, con stant' engagement with said last mentioned gear on the drive shaft, means for controlling operation of said quick return shaft, a slow feed shaft, a worm on said slow feed shaft, a worm gear loosely mounted on the drive shaft intermediatethe ends thereof and engaged by said worm, and means for coupling said worm gear'to the drive shaft.

2. In combination with a screw plunger, a drive gear provided with a sleeve surhavinga longitudinal slot therein, a trans-- .verse key upon the screw plunger extending through said slot in the sleeve, power operated mechanism for rotating the gear, a throw-off device for-rendering said power mechanism inactive, and tripping means for saidthrow-oif device having an annular portion about the sleeve in position to be engaged by the transverse key aforesaid. V

.3. In combination, a screw plunger, a gear provided with a sleeve surrounding the end of the screw plunger-,said sleeve having a longitudinal slot therein, a transverse key upon the screw plunger extending through said slot in the sleeve, power operated mechanism for rotating the gear, a spring operated throw-off device for rendering the power-mechanism inactive, a springlatch for holding said throw-off deviceinoperative, and a pivoted trip lever connected with FRANCESCO GENOVESE.
